  • Applications

    1,1-Dichloroethylene, CAS 75-35-4, is mainly used as a monomer for polyvinylidene chloride (PVDC), a polymer with high barrier properties. PVDC and PVDC-based coatings and films are used in food packaging as films and laminates to improve oxygen and moisture barriers. It can also be copolymerized with other monomers to tailor barrier and mechanical properties of coatings and films. It also serves as an important intermediate in the production of specialty polymers and industrial coatings. Additionally, 1,1-Dichloroethylene is commonly considered as a building block in organochlorine synthesis and related polymer systems.
